The term "hatch" or "hatches" is applied to wall or ceiling access hatches in regular use and are either hinged or screw fixed.
Ceiling access hatches, for example, are common and essential elements for daily inspection routines to most E&M services within fire compartments and routine maintenance programmes in most buildings.
access panels and hatches are approved in a range of sizes and fire resistance, offering flexibility for any type of opening in substrates such as walls, floors or ceilings.
The hatches are easy to install and can be finished or decorated to suit the surrounding building elements.
The types of fixing for these panels and hatches largely depends on the area of application, frequency of carrying out maintenance, appearance and the weight of the panels/hatches.
Hinged ceiling access hatches are usually pre-fabricated in a standard size of 600mm x 600mm. The hatches can also be custom-made to specified dimensions, depending on size and quantity.
Fire resistance testing for Promat's ceiling access hatches are conducted in Australian Standard AS1530: Part 4, or British Standard BS476: Part 20 & 22.
